FAQs
The P3BEDH3125GN is a 3-pole plug-in unit built for Pow-R-Way III busway systems with an EDH frame. It mounts as a plug-in protection device within EDH-based busways, enabling straightforward commissioning, minimal field wiring, and reliable phase protection. This compatibility supports scalable modular deployments and reduces retrofit complexity when expanding busway protection in industrial facilities.
Key specs include a 125A amperage rating and a 100 kAIC interrupt rating at 240 VAC, ensuring it can safely interrupt high fault currents typical in motor-driven lines. The unit also offers 50% internal grounding and 100% neutral, enhancing fault clearance and return paths, which improves overall system stability during faults or abnormal conditions.
This plug-in unit is ideal for industrial power distribution where Pow-R-Way III busways are used to connect feeders, motors, and drives. It is well-suited for manufacturing lines, packaging systems, conveyors, data centers, and other facilities requiring reliable, scalable protection with quick plug-in replacements and regulatory compliance.
The unit carries IEEE Certified, CSA Certified, ANSI, and UL 857 listings, which corroborate compliance with recognized safety and performance standards. These certifications reduce procurement risk, simplify audits, and help ensure safe operation in varied regulatory environments. NEMA compliance is also indicated, supporting broad compatibility with typical industrial enclosures and systems.
Installation is streamlined by plug-in design, reducing commissioning time and downtime during replacements. The 125A rating and high interrupt capability protect critical loads, lowering the risk of costly motor damage. Over time, quicker maintenance and modular upgrades translate to lower total cost of ownership and improved uptime for production lines and facilities.
